Source Device
The Shelly 1 is a compact Wi-Fi relay with dry contacts, designed for switching AC (110-240 VAC) or DC (12-60 VDC) loads up to 16A AC / 10A DC. It offers Wi-Fi connectivity (802.11 b/g/n), supports schedules and webhooks, and integrates directly with Home Assistant without a hub. Its small size allows for installation in wall boxes, making it suitable for retrofit applications. It is known for its flexible power supply options and local control capabilities.
Top Alternatives
- Shelly 1 Gen4: The Shelly 1 Gen4 is the direct successor to the Shelly 1, maintaining its core functionality as a compact smart relay with dry contacts. It offers enhanced features like multi-protocol connectivity (Wi-Fi, Zigbee, Matter, Bluetooth), an improved processor for faster responses, and continued strong Home Assistant integration. It supports both AC and DC power supplies and fits in standard electrical boxes.
- SONOFF MINI-D (MINI Dry Wi-Fi Smart Switch): The SONOFF MINI-D is explicitly designed as a Wi-Fi dry contact smart switch, making it a direct competitor to the Shelly 1. It supports both AC and DC power supplies, is Matter-certified for broad interoperability, and is compact enough for various installations. It's ideal for controlling motors, garage doors, and other dry contact input devices.
- Tuya Smart WiFi Dry Contact Switch Module: These modules provide dry contact switching via Wi-Fi, similar to the Shelly 1. They are widely available, often at competitive prices, and integrate with the popular Tuya Smart/Smart Life app, which in turn can be integrated with Home Assistant. They typically support AC (100-240V) and sometimes DC (12/24V) power, making them versatile for various applications like garage doors, gates, or boilers.

Operator Notes
- The Shelly 1 is a well-regarded device for its dry contact capabilities and local control. The alternatives focus on similar functionality and Home Assistant compatibility.
- Dry contacts are crucial for applications where the relay needs to switch a circuit without providing its own voltage, such as garage door openers, boiler controls, or alarm systems.
- When evaluating alternatives, special attention was paid to explicit mentions of 'dry contacts' or 'potential-free contacts' to ensure direct comparability. Devices requiring physical modification to achieve dry contact functionality (e.g., some Sonoff Basic models) were generally excluded from the top alternatives, as the user requested 'real comparable products' rather than DIY hacks.
- Pricing and availability were checked on Amazon and Alibaba (or AliExpress for Shelly/Sonoff) to reflect current market conditions as of April 10, 2026.
